Estimating of combining ability is useful to assess genotypes and elucidate the nature and magnitude of gene actions involved. Aim of this study was to determine the combining abilities of some wheat genotypes for yield and some yield related traits by using line × tester mating design. Four advanced wheat lines and one cultivar were used as lines and four wheat genotypes were used as testers. The specific combining ability (SCA) effects were generally found higher than general combining ability effects (GCA) in terms of the agronomic traits studied. As a result, low ratios of , and low narrow sense heritabilities showed that non-additive effects controlled the traits studied. Hence, the selection process for superior individual plants should be postponed to further generations like F 4 or F 5.

Barley has higher adaptation capability even in so dry areas then could be grown in many parts of the world. Barley which mostly produced for animal feed and malt is one of the most produced cereals and main rotated crops especially rainfed areas in Turkey. Trakya region which is European part of Turkey is one of the most cereal produced areas and growing the most bred animals. Therefore, barley produces as the main cereal crop especially in dry areas other than wheat like other part of Turkey and exists as the main crop in the rotation for mostly animal feed. To evaluate of some barley cultivar performances in Trakya Region, the study was performed in 2010-2020 growing season in Edirne and Tekirdag Malkara locations. The candidate barley lines and standard commercial cultivars which are the most planted ones in the Turkish market existed in seed yield trials in the study. Based on study results, three barley candidate lines exhibited higher seed yield performances over all standard cultivars. The candidates also were better than standard cultivars for quality traits. As conclusions, TRAGEN Ltd candidate barley lines exhibited promising results then the best ones will be selected for registration in next years.

Wheat is the most planted crop as well as the most important food and the main crop in the rotations in Turkey. Wheat grows in all parts of the Turkey and Trakya region which is European part of Turkey exist at the 3 rd region after Middle and Southeastern Anatolia. Clearfield System which is developed by BASF with combination of IMI (Imidazolinone) herbicide and resistant varieties started firstly in corn, but currently IMI sunflower, canola, rice, wheat, etc. were cultivating by farmers widely in the world. In Turkey, Clearfield system exist only in sunflower and rice not in the wheat yet. IMI wheat could be good solution for proper weed control in especially some areas which were invaded by some perennial grassy weeds. TRAGEN Research Company which is in Trakya Technopark, Edirne, Turkey started first time in Turkey IMI resistant wheat cultivar breeding program. The study was conducted to test performance of some IMI type wheat cultivars in Trakya Region conditions in 2019-2020 growing season in Edirne and Tekirdağ Malkara locations. The experiments were conducted with four replications with five control wheat cultivars which are the most planted and preferred wheat cultivars in Trakya Region. The study results indicated that some IMI cultivars exhibited higher seed yield performances over control cultivars. The promising candidate IMI lines after evaluating quality and yield performances will be sent to registration trials then to produce in Turkish seed market.

Bread wheat is a main and widely grown crop throughout Turkey. Because of having higher adaptation capability, growing in almost all kind of soil and consuming larger by people, it makes to wheat is the most important case in the agriculture and the most important issue in the human life in Turkey. Trakya region which is European part of Turkey is one of the main wheat grown areas in Turkey. The study was performed to measure some wheat lines and cultivar performances in Trakya Region in 2019-2020 growing season. Yield trials were planted at two locations as Edirne and Lüleburgaz Kırklareli and the candidate bread wheat lines existed in yield trials with five control wheat cultivars as Pehlivan, Gelibolu Rumeli, Esperia and Flamura-85 cultivars which are mostly planted and preferred by farmers and industry in Trakya Region. The experiment results indicated that some candidate lines exhibited over yield performances than control cultivars. TRAGEN YK-6 was existed in top rank in Edirne location while Klima was in Lüleburgaz location. The candidate lines were also evaluated and compared with control cultivars based seed and flour quality results. As results, TRAGEN Ltd wheat cultivars had favorable results based this study and promising ones will be tested again future trials and selected ones will send to registration trials to produce and then exist in Turkish seed market.
